Reporting for the first time as a public company, T-Mobile is back in the subscriber black, after reporting 1.1 million net new customer additions during its fiscal second quarter.

The fourth largest U.S. cell network, which completed its merger with MetroPCS in May and changed its name to T-Mobile US, also added another 8.9 million customers from the acquisition. In terms of raw growth, 685,000 new customers landed from its post-paid base.
